Configuring multicast routing and forwarding
Configuration prerequisites
Before you configure multicast routing and forwarding, complete the following tasks:
Configure a unicast routing protocol so that all devices in the domain are interoperable at the
network layer
Enable PIM (PIM-DM or PIM-SM)
Determine the maximum number of downstream nodes for a single multicast forwarding table entry
Determine the maximum number of entries in the multicast forwarding table
Configuring multicast static routes
By configuring a multicast static route for a given multicast source, you can specify an RPF interface or an
RPF neighbor for multicast traffic from that source. If you want to remove a specific multicast static route,
use the undo ip rpf-route-static command, if you want to remove all multicast static routes, use the delete
ip rpf-route-static command.
To configure a multicast static route:

Command Remarks
1. Enter system view. system-view N/A
2. Configure a multicast static
route.
ip rpf-route-static source-address { mask |
mask-length } [ protocol [ process-id ] ]
[ route-policy policy-name ]
{ rpf-nbr-address | interface-type
interface-number } [ preference preference ]
[ order order-number ]
No multicast static route
configured by default.
3. Delete multicast static routes. delete ip rpf-route-static Optional.
CAUTION:
W
hen you configure a multicast static route, you cannot specify an RPF neighbor by providing the type
and number (
interface-type interface-number
) of the interface if the interface of the RPF neighbor is a
Layer 3 Ethernet interface, Layer 3 aggregate interface, Loopback interface, Layer 3 RPR logical interface,
or VLAN interface. Instead, you can specify such an RPF neighbor only by its address (
rpf-nbr-address
).
Configuring a multicast routing policy
You can configure the router to determine the RPF route based on the longest match principle.
By configuring per-source or per-source-and-group load splitting, you can optimize the traffic delivery
when multiple data flows are handled.
To configure a multicast routing policy for the public network:

Command Remarks
1. Enter system view.
system-view N/A
2. Configure the device to select the
RPF route based on the longest
match.
multicast longest-match
The route with the highest
priority is selected as the
RPF route by default.
